Cilium is an open-source networking and security solution for cloud native environments. It is built using eBPF (Extended Berkeley Packet Filter) technology, which enables it to provide superior performance, scalability, and observability. In this explanation, we will explore some specific use cases of Cilium, including securing microservices, containerized workloads, and multi-cloud environments.
Securing Microservices
Cilium provides robust security for microservices by enabling identity-based policy enforcement that is decoupled from network addressing. This means that policies can be defined based on the identity of the workload, rather than its IP address, which simplifies policy management and reduces the risk of misconfigurations. Cilium also supports Layer 7 (L7) policies, which allow for more granular control over traffic based on HTTP headers, URLs, and other application-level metadata.
